Embodiment Construction

[0012] Such as figure 1 As shown, the construction hoist includes a plurality of standard sections 1 and cages 2 installed on the standard sections 1. These standard sections 1 are overlapped in turn to form the required height. The upper column 101 rises or falls, thereby carrying workers or equipment to the floor of the corresponding height. Between the cage 2 and the column 101, the guide wheel group 201 positioned on the side of the cage 2 is used for rolling guide cooperation, such as figure 2 As shown, the left side of the hanging cage 2 is provided with two guide wheel sets 201, wherein the guide hole of one guide wheel set 201 cooperates with the front column 101 on the right side of the standard section 1, and the guide hole of the other guide wheel set 201 Cooperate with the rear column 101 on the right side of the standard section 1, like this, the cage 2 is multi-directionally limited by the two guide wheel sets 201, so that the cage 2 can only move in the vertic...

Abstract

The invention discloses a guide device for safely locating a construction hoist cage and an installation method for the cage. The guide device facilitates installation of the cage and solves the problem of potential safety hazards. The guide device comprises a cylindrical body formed by an upper portion guide section, a middle guide section and a lower portion locating section, wherein the upper portion guide section, the middle guide section and the lower portion locating section are coaxially arranged. The upper portion guide section of the cylindrical body is of a cone-shaped guide structure. The middle guide section is matched with a guide porthole formed by a guide wheel set of the construction hoist cage. The lower portion locating section is matched with an upper pipe orifice of a standard-knot stand column of a construction hoist. After the lower portion locating section extends into the pipe cavity of the stand column, a side gap is formed between the lower portion locating section and the inner pipe wall of the pipe cavity and enables the cylindrical body to deflect at the upper end of the stand column in a small-angle mode. The diameter of the lower portion locating section is smaller than that of the middle guide section, so that a locating step used for being meshed with the end face of the upper pipe orifice is formed on the joint portion of the middle guide section and the lower portion locating section. By means of the guide device, the location difficulty of the cage is lowered, and the danger such as pinching of hands can be avoided.

Description

technical field [0001] The invention relates to a safe positioning guide device for a construction hoist cage and an installation method for the cage. Background technique [0002] In recent years, construction elevators have been widely used as vertical transportation machinery in building construction, and safety accidents of construction elevators have also occurred continuously. Especially in the installation process of the construction hoist, mechanical injury accidents are particularly prone to occur when the hanging cage is installed in place and inserted into the standard section. The cage is the carrying equipment in the construction elevator. It has large dimensions and heavy weight. It is usually equipped with two sets of guide wheels. Each set of guide wheels is composed of multiple guide wheels and forms guide holes. The standard section of the construction hoist is matched with the column, so that the lifting and lowering of the cage is guided vertically throu...
